Er Toshtuk (Sir Toshtuk), a magical and darkly humorous theatre piece, is based on one of the oldest Kyrgyz epics about a journey into the underworld and out into the cosmos. Toshtuk, a young warrior, falls into the Underworld and must battle giants, monsters and a killer cauldron as he grows up, finding love and loyal friends. The tale is a part of the cultural heritage of the people of Kyrgyzstan, a land of nomadic horsemen, whose memory is rich with the mythical adventures of ancestral warriors.
